I searched on this site for Windows 3.1 drivers for this card and found none so I emailed tech support at ESS. Somebody there was actually nice enough to send me the drivers via email (the drivers aren't on their website anymore)! However, I didn't like their implication that DOS/Windows 3.1 is obsolete and I should move on to a newer system. For those of you that still enjoy your old, obsolete systems, good for you! Enjoy the drivers!
